«By stacking multiple
photodiodes on top of each other in silicon, we can see color without the use of special filters.
Not exact matches
Digital cameras create images based
on data from millions of
photodiodes, each of which measures the amount of light it receives.
Instead of catching light
on film, digital cameras use an array of light - sensitive
photodiodes that function much like the photoreceptors in an eye.
As long as the sensor is in place, nothing will change, because every one of the million
photodiodes will go
on reporting its own separate dot, unaware of what its peers are seeing.
Then stand the
photodiodes well ordered
on a square array, and let each tell light from dark for its own dot, as precisely as it will; nowhere will there be a consciousness of the whole picture, said Galileo.
It was not clear whether Alturi liked this, but then he said: «I guess when you apply this analysis to the sensor of the camera, it will break down into complexes that are individual
photodiodes, each of them distinguishing between just two states,
on or off, but there will be no integrated entity — a complex — corresponding to the sensor.
Most semiconducting optoelectronic devices (OEDs), including
photodiodes, solar cells, light emitting diodes (LEDs), and semiconductor lasers, are based
on inorganic materials.
